When switching between Linear and Gamma color space, lighting information is passed but Light Probes themselves are not updated. The switch between Linear Color and Gamma color space takes remarkably longer (approx. 5 seconds) than the version 5.4. It is working as expected in 5.4.0p25, 5.4.0f2. The issue appears in 5.5.0a4, 5.5.0a5 and 5.5.0a6.

Steps to reproduce the bug:

1) Open the scene 'TestScene'.
2) Build the lighting.
3) Open File > Build Settings > Player Settings.
4) In Other Settings > Rendering, change color space from Linear to Gamma or vice versa.
5) Observe the bug.
